Definitions

  • the upper ends of the inflatable bladder and ⁇ bs are secured relative to the body, while the lower ends of the bladder and reinforcing sheath are secured to a seal which is movable relative to the body
  • the movable seal responds to inflation forces and allows the inflation element to expand without causing damage to any of its component pans
  • U.S. patents 5,469,919, 5,564,504 and 5,813,459 also discuss pinching seals, bladder folding, rib kinking, and rib cutting of the bladder.
  • These patents describe the use of structural elements along the length of the bladder to cause relatively uniform expansion such that the ratio of the largest diameter of the bladder to the smallest diameter during inflation is always below a pre-determined maximum value.
  • the designs in these patents resulted in elements with more uniform expansion, they did not completely eliminate the occurrence of folds, rib kinking, rib cutting or the occurrence of high tri-axial strains in the bladder.
  • Figure 4 is a schematic view of a thin strip of elastomeric material being wrapped onto a mandrel to form a bladder or cover section;
  • Figure 5 is a schematic view, partially in section, of a bladder or cover section formed as shown in Fig. 4, being cured in an oven;
  • the inflation element 10 includes upper and lower end collars 12, 14, respectively.
  • the bladder 16 is expanded and contracted through the introduction and withdrawal of pressurized fluid in a way that is well known.
  • the bladder 16 is sunounded by and secured to a reinforcing sheath formed of a plurality of longitudinally extending slats or ribs 18, which are also well known.
  • a reinforcing sheath formed of a plurality of longitudinally extending slats or ribs 18, which are also well known.
  • Each of the ribs 18 overlaps the next adjacent rib when the bladder 16 is deflated.
  • Each rib also adequately overlaps the next adjacent rib when the bladder 16 is inflated forming a protective structural sheath over the bladder 16. Exposed sections of the ribs 18 also operate to anchor the tool in a well bore.
  • pre-disposing the bladder 34 prior to inflation for aligning the long axis of the molecular chains that make up the elastomer from which the bladder is formed, as discussed above.
  • One aspect of pre-disposing the bladder includes the process of forming the bladder.
  • bladders have been formed in the prior art is by extruding the elastomer used to form the bladder into a shape suitable for the bladder. This method has proved to be unsatisfactory in forming a bladder that is resistant to tearing because the molecular chains of the elastomer are aligned with the long axis of the inflation element. As discussed above, the chains are not aligned in the direction of principal strain, which results in a bladder that is less resistant to the propagation of tears in the longitudinal direction of the bladder. Thus, the bladder should be formed by wrapping strips of elastomer around a mandrel that is either cylindrical or shaped in way that influences the inflation profile of the bladder.
  • cover sections could be pre-disposed in a similar manner with a desired profile before they are installed onto an inflation element.
  • a method has been provided in accordance with the invention, and a shaping tool or vessel formed in accordance with the method, where the expansion profile of a downhole inflation element is pre-disposed.
  • This pre-disposition tends to make the bladder more resistant against folding and pinching, as well as providing a more uniform expansion along the length of the inflation element for enhanced performance.

Abstract

La présente invention concerne un procédé servant à prédisposer un gabarit d'expansion (68) dans un élément élastomère déployable d'un outil de fond. Ce procédé consiste : (a) à envelopper au moins une partie de la longueur d'un élément élastomère avec un outil (72, 74, 76) ou un récipient de formage dont le diamètre intérieur définit une limite profilée servant à prédisposer un gabarit d'expansion dans l'élément; (b) à appliquer un fluide sous pression (78) sur l'élément élastomère pour le gonfler et le mettre en contact avec le diamètre intérieur de l'outil de formage afin de créer un gabarit d'expansion prédisposé dans l'élément; et (c) à réduire la pression du fluide pour permettre à l'élément élastomère de reprendre généralement sa forme originale. L'invention concerne aussi un outil de fond muni d'un élément élastomère déployable amélioré, lequel définit un gabarit d'expansion prédisposé.
